Q: Can I convert to GIF?
A: We don’t support GIF yet, but we’re considering it. For now, try using a dedicated GIF tool after conversion.

Q: Does RunConvert work in all browsers?
A: Yep! Chrome, Firefox, Safari, Edge—we play nice with all the modern ones.
Q: Can I reduce background noise through conversion?
A: Conversion alone won’t clean the audio. For that, try an audio editor before or after the conversion.
Q: Why is my converted video larger than the original?
A: It happens if the output format uses less compression or adds metadata. You can tweak the resolution or bitrate to fix that.
Q: Will subtitles stay synced after conversion?
A: If they’re embedded, yes. If they’re external (like .srt), they might need re-syncing.
Q: Why is my video blurry after conversion?
A: It might be set to a lower resolution or bitrate. Try converting again with higher settings.
